Through my own incompetence I've just had to recreate my registry, s'OK I took a backup first.  Ran regedit /c:filename from a command prompt only boot up, worked OK but took 13 (thirteen) hours.  Is this indicative of a problem or quite usual.  System.dat and  User.dat total 8.3MB.  If this is a big problem I'll up the points.

1. Try a registry cleanup, AFTER making a backup. Use this handy tool RegSupreme:

http://www.jv16.org/

2. Optimise your registry:

Bootup with a startup floppy disk and at the A:\> prompt type

scanreg /fix /opt (space between g and /, and x and /)

Press enter, wait for the process to finish and reboot WITHOUT the disk.

If you don't have a startup floppy disk, download one from www.bootdisk.com.

That should thin down your registry.

Hi Zee

Thanks for the info, I already have jv16 power tools and run the registry cleaner regularly.  Their registry manager list of installed software shows 248 entries, I'm sure some of these are defunct, but I'm not sure which ones.

I'll disappear for a while and run the scanreg as suggested then let you know what happened.

Hi Zee,

OK, no great reduction in size (about 10KB on both .dat files), which, as occurred to me whilst running Scanreg, is not really surprising as I run Norton SystemWorks Registry organiser on a weekly basis.  In fact I defrag both hard drives weekly as well, I check with Spybot, Ad-aware and Kaspersky AV and I'm behind a firewall, so I *hope* there isn't too much trash on my PC.

Over 5 years I suspect that my registry has collected a lot of unnecessary entries, but I don't know for sure which ones they are.  I know I can delete entries in the registry using the list of installed software in jv16 but, if I'm looking at half a day plus to recover from any error I'm not very keen to take chances.

Is it possible to resore part of a registry rather than all of it?

If you run RegSupreme, it will automatically select the obsolete entries.

You select them and click FIX or similar wording and it will prompt you to backup (DO SO!!!).

Let it clean your registry, reboot and check.

FIY: the first time I used RegSupreme it found 1,500+ obsolete entries. I deleted them and had no reason to regret it.

RegSupreme A super fast, lightweight standalone registry cleaner.

(Contains only the registry cleaning engine from jv16 PowerTools)

(The above is cut and paste from their web site)

It isn't called RegSupreme within PowerTools but it must be the same thing, it deleted 1827 entries the first time I ran it, I didn't haven't a problem deleting those and still delete the odd ones it finds now.  But within PowerTools there is also a tool called Registry Manager, which may or not be included in RegSupreme.  (This part of PowerTools is very similar to a package called RegCleaner by Jouni Vouorio.)This can list, among other things, "all software registered to my registry" and this is where I'm unsure what's safe, and what's not, to delete.

I'm getting the impression that my registry is about as trimmed down as anything automatic can make it, so if I want to go further it will have to be manual.

STOPPRESS  Just realised that within regedit GUI I can backup individual keys, from this I presume that,should I screw up badly enough to not be able to reboot and as long as I know which key I've damaged and where I put the backup, I would be able to restore just that key, which presumably wouldn't take much time.

The  only bit I can't find is the correct format for the regedit command line switches to restore one key at a time, and should it be insert or restore. (or whatever the options are).

Thanks for the info on RegSupreme.

I wouldn't play with fire...

>>"all software registered to my registry" and this is where I'm unsure<<

You have reasons to be unsure. If you want to trim these entries you MUST be absolutely SURE of what you're doing.

The good news:

You are about right when it comes to size (ROFL...), my user.dat and system.dat are about 7.6MB.

Considering you probably have more software installed in your rig than I do, I would say you should not worry.

Cheers,

Zee

That sounds like good advice to me, I should be old enough to know that you don't fix it if it ain't broke, but sometimes I've just *got* to tinker.

Thanks for the help.
